Dushku has now revealed that there will be chemistry between her character Raquel and Neal (Matt Bomer).

"What was interesting to me was that she was almost the female version of him," she told TV Guide. "I just think it's sort of an irresistible sort of connection where they are so much alike and they are both just extremely charged and primed for each other, even if they weren't expecting it."

Dushku added that the connection between the pair was the reason she agreed to the role.

"I wanted a Mr & Mrs Smith vibe," she explained. "[I said] I'd love to come and be on it, but only if it's something that's really special and only if Raquel and Neal really have a Mr & Mrs Smith dance going on. It could be sexual at times, it could be violent and scary at times, but as long as it's intense, and [executive producer Jeff Eastin] really responded to that."

However, Dushku admitted that she isn't sure whether she will reprise the role in future, saying: "We just have to see what kind of arc they have in mind. It's definitely a pretty exciting stand-alone episode, but the door is open and we'll see what they have in mind."
